As a plastic coated paper product, coated paper cups will also be included in the "prohibited plastic" category. Coated paper cup paper is to pour a layer of plastic film on the base paper of the paper cup. While improving the liquid resistance of the paper, the coated paper cup paper can also be heated and bonded to form a paper cup, but the plastic film is not easily degraded and is harmful to the environment. Therefore, major paper cup and paper manufacturers are looking for a degradable raw material to replace the plastic coating on the coated paper. At present, the most researched and applied coatings are plastic-free coatings.
Plastic-free coated paper cup paper is uniformly coated with liquid coating on the surface of the paper cup base paper through various coating processes. After heating and drying, a coating film is formed on the paper surface to meet the use requirements of paper cup paper. In comparison, non-plastic coated paper cup paper should have the following properties:
(1) While meeting the safety and sanitation index requirements of food contact articles, it can degrade by itself after a period of disposal to achieve green, ecological and environmental protection purposes.
(2) It has excellent barrier and impermeability properties for various drinks, including hot and cold drinks, such as milk tea, tea, Coca-Cola, and acid coffee, fruit juice, and even storage of various alcoholic products.
(3) In order to make use of the existing cup-making equipment and ensure the good formability of the paper cup, the plastic-free coating should have good heat-sealability, that is, the plastic-free coating film and the coated plastic film have similar hot melt properties. In addition, coating is required. The film has better printing adaptability after surface tension is improved.
